1"3Claims, (01. 30-53) This invention; relates torazors :andmoreparticularly to safety razors 0f the classtin which the blade has a thickened rear .portion'ito which a handle, either for shaving .orlfor strapping and honing, may be attached. In other words, the invention relates to razors of the class ,disclosed in IT. S. Patent vNo. 2,357,601, issued to me :September 5, 1944. One such razor is the Rolls, ;in which the thickened rear portion of :the .blade :is provided with .a socket having iinternal iprojections arranged to :interlo-ck with projections on a stud carried by .a handle.

Themachining of th socket with its'internal projections is a diflicult and relatively costly -operation. The same is true of the stud. "The presentinvention is concerned witha novel and improved construction in which the socket or bearingin which th stud or pivotxturns is'with- .out any internal projections, and in practice is merely a drilled hole, much lessldiflicultxandcost- 1y to produce than one with internal projections.

The invention will be understood byxreference to the following-description when taken :incon-' nection with the accompanying drawing ofsome specific embodiments thereof, whileits scopewill be pointed out more particularly in the appended claims.

In the drawing:

Referring to the drawing :and to the embodiment of the invention illustrated in'Figs. i to 4 inclusive,'thereisyshown 'an example in which a blade I2 is provided with a cutting edge l4 and a thickened rear portion [6 which serves for the attachment of a handle [8 by novel means now to "be described, reference being had at first more particularly to Fig. 2.

The connection between the blade and the handleincludesa pivot 20, preferably cylindrical, and a bearing 22 therefor which is simply a drilled hole and henc easily and inexpensively machined. In this example the hole is inclined to the cutting edge, and advantage is taken of this fact to hold the pivot in place in its bearinginthe manner presently to be explained.

The handle is connected to the ivot bya shank 24, which normally interengages with the blade to resist turning of the pivot in its hearing. In this example, this is conveniently accomplished by making the shank :with a rounded, or cylindrical, portion 26 normally received in a depression 28 inithe blade. The shank has a relatively thinner, flexible-or resilient portion 3.!) capable of springing and thus permitting the portion 26 of the shank to :rise outof the depression 28 when suificient force is applied to swing the handle l8 about the axis of the pivot 29. Conversely, whenrestoring the handle to its normal position, one or two inclined ramps 32 (see Fig. 4), herein two ramps at .opposite sides of the depression zli, cause the resilient portion 30 to flex and the'portion 26 to rise and ride up the ramp and then snap into theldepression 28.

; From acomparison of Figs. 2 and 3, it willbe observed'that the pivot 20 is at anobtuse angle to the handle and that owing to this obtuse angle, in swinging from the position shown in Fig. 3 in-which the pivot can be withdrawn-from the bearing .to the normal position shown in Fig. 2, the shank portion 26 descends as it swings and encounters one of the ramps-32. At this stage the .pivot 20 should beheld firmly in thebearing as the portion 28 ofthe shank 24 rides up the reason of the fact that the handle cannot swing aboutthe axis of .the'pivot. The handle may therefore be made use of in honing or stropping the :blade. In the case of a handle for, shaving (see Figs. 8 to 11 inclusive) similar construction is employed, the handle and the blade with its angular bearing and the pivot turning therein, as well as the depression and the ramps, are the same .as before, but the depression receives a resilient arm 34 which projects laterally from the While the described arrangement including the angular pivot and bearing suffices in and'vof itself and without other aid to accomplish the attachment of the handle to the blade when the-pivot is pressed inwardly during assembly, there may be added means to make such pressure unnecessary as by a lip 36 above the pivot and underlying a shoulder 38 above the bearing (see Fig. 5)

ments of the invention, what I claim is:
